I missed a call from this number, but when I called back (from a different phone) it said the number was either incorrect or not connected. I'd say this is a scam so don't answer the call.

Caller: Scam

Amazon scammer. Left a voicemail that I have to pay something to Amazon. I don’t use Amazon at all. Keep calling under different numbers starting with 0480003###

I also received 0480 003 134 & 0480 003 286 the same day I believed it's a scam of these call.
